Overview, Continued Qualified Personnel Only appropriately qualified and trained personnel should install, operate, maintain, and service this product. WARNING: Allow only qualified personnel to install, operate, maintain, and service this product. Otherwise, personal injury or equipment damage may occur. In These Installation Instructions These installation instructions contain the following topics.
Important Safety Instructions Read and Retain Instructions Carefully read all safety and operating instructions before operating this equipment, and retain them for future reference. Follow Instructions and Heed Warnings Follow all operating and use instructions. Pay attention to all warnings and cautions in the operating instructions, as well as those that are affixed to this equipment.
Important Safety Instructions, Continued This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
Laser Safety Introduction This equipment contains an infrared laser that transmits intensity-modulated light and emits invisible radiation. Warning: Radiation WARNINGS: • Avoid personal injury! Use of controls, adjustments, or performance of procedures other than those specified herein may result in hazardous radiation exposure. • Avoid personal injury! The laser light source on this equipment emits invisible laser radiation. Avoid direct exposure to the laser light source.
Laser Safety, Continued Safe Operation For Software Controlling Optical Transmission Equipment If this document discusses software, the software described is used to monitor and/or control ours and other vendors’ electrical and optical equipment designed to transmit video, voice, or data signals. Certain safety precautions should be observed when operating equipment of this nature. For equipment specific safety requirements, refer to the appropriate section of the equipment documentation.

Configuration Instructions Introduction The Prisma Gigabit Ethernet Media Converter modules have user-configurable features. Refer to the table in Switch Configuration Table later in these instructions for available features. Instructions for configuring both managed (via an SNMP-compatible management application like PrismaView™ ) and unmanaged modules follow.

The diagram below shows the switch location on the module. The chart below states the available features and settings for the module.
About LinkLoss and FiberAlert Introduction The Prisma Gigabit Ethernet Media Converter modules include the troubleshooting features FiberAlert and TX LinkLoss that help locate "silent failures" on your network. It is vital to understand how FiberAlert and LinkLoss work, and how they will react in your network configuration, before attempting to install the module(s).
About LinkLoss and FiberAlert, Continued What Is FiberAlert? FiberAlert minimizes the problems associated with the loss of one strand of fiber. If a strand is unavailable, the device at the receiver end notes the loss of link. The device then stops transmitting data and the link signal until a signal or link pulse is received. The result is that the link LED on BOTH sides of the fiber connection will go out indicating a fault somewhere in the fiber loop.
Additional Gigabit Features Master/Slave Mode This Master/Slave mode feature determines which clock will be used between the Prisma Gigabit Ethernet Media Converter module and the device it is connected to (a switch, NIC, or another Prisma Gigabit Ethernet Media Converter module, etc.). Slave mode is the default setting. In Slave mode, the module receives and uses the clock of the connected device. Master mode uses the module's clock. The Master/Slave mode is only valid for the twisted pair link.

Installing the Prisma Gigabit Ethernet Media Converter Module Introduction Prisma series modules install in an SNMP-manageable Prisma MediaCenter chassis or in Prisma MediaCPE chassis. Installing the Module Follow these steps to install a module. 1. Remove the blank bracket covering the slot where the module is to be installed by removing the screws on the outside edges of the bracket. 2. Slide the module into the chassis, via the card guides, until the module is seated securely in the connector. 3.
Fiber Optic Cleaning Guidelines Optical Connector Cleaning Overview Cleaning fiber-optic connectors can help prevent interconnect problems and therefore aid system performance. When optical connectors are disconnected and reconnected, the fiber surface can become dirty or scratched. The goal of cleaning the fiber optic connectors is to remove all dust and contaminants without leaving any residue. Required Equipment The following equipment is required to clean the ends of fiber-optic connectors.
Fiber Optic Cleaning Guidelines, Continued Cleaning Optical Connectors WARNING: Avoid personal injury! Use of controls, adjustments, or performance of procedures other than those specified herein may result in hazardous radiation exposure Avoid personal injury! The laser light source on this equipment emits invisible laser radiation. Avoid direct exposure to the laser light source.
LED Operation Prisma Gigabit Ethernet Media Converter Module Front Panel The following illustration shows the Prisma Gigabit Ethernet Media Converter module front panel. Prisma Gigabit Ethernet Media Converter Module Front Panel Components The Prisma Gigabit Ethernet Media Converter module features diagnostic LEDs that provide information on features and ports. LED LNK/ACT Description • Glows green when a twisted pair link is established. • Blinks green when data is detected on the port.
LED Operation, Continued LED Description • Glows amber when port is operating in Full-Duplex mode. FDX • Located on RJ-45 connector. 18 FA Glows green when FiberAlert is enabled. TX LL Glows green when TX LinkLoss is enabled on the port. LNK Glows green when a fiber link is established. MASTER Glows amber when operating as a Master.
Installation Troubleshooting Troubleshooting • During installation, first test the fiber and twisted pair connections with all troubleshooting features disabled, then enable these features, if desired, just before final installation. This will reduce the features’ interference with testing. • When working with units where the features cannot be disabled, you must establish BOTH your twisted pair and fiber connections before the link LEDs will illuminate.
